CORONADO, Calif. — It is easier to put in a small tube than to do a trabeculectomy flap, Paul Palmberg, MD, PhD, said, referring to the use of a transscleral micro-lumen aqueous drainage device for lowering IOP.

The InnFocus MicroShunt drainage device is an 8.5 mm long tube with a lumen diameter of 62 µm to 70 µm intended to deliver a predictable lower limit of pressure that should avoid persistent hypotony, once aqueous flow returns to normal, Palmberg said.
